NAMEpccard - PC Card bus driver
SYNOPSISdevicepccardDESCRIPTION
The pccard driver implements the PC Card bus. The pccard driver supports
all PC Card bridges in the system.
TUNABLES
The driver supports the following tunable parameters, which may be added
to /boot/loader.conf or set via the sysctl(8) command:
hw.pccard.debug Non-zero values cause more verbose information
to be printed when a 16-bit PC Card is inserted
or removed.
hw.pccard.cis_debug Non-zero value causes the CIS parsing of the
16-bit PC Card to be much more verbose and
include a complete CIS dump.
FILES/dev/pccard0.cis This exclusive-use device will report all the CIS
chains present in a PC Card, if a 16-bit PC Card is
inserted in the slot. Only one user at a time may
access the CIS. The CIS is presented as the
relevant byte stream from the PC Card. For CIS
tuples in Attribute Memory (the default), only the
even locations are presented (the ODD locations are
undefined per the standard). For CIS tuples in
Common Memory, every byte is presented to the user.
Decoding of the CIS tuples is done via a userland
program. All tuples are presented to the user.
